A method for operating a self-igniting internal combustion engine
includes: introduction of a prespecified pre-injection quantity (PI) of a
fuel into the internal combustion engine before and/or during an
intermediate compression; determination of a pressure characteristic
(PZV) in the internal combustion engine during the intermediate
compression; prespecification of a target pressure characteristic (PZV0);
comparison of the determined pressure characteristic (PZV) with the
prespecified target pressure characteristic (PZV0); determination that no
release of energy occurred during the intermediate compression, provided
that the determined pressure characteristic (PZV) is lower than the
target pressure characteristic (PZV0); and compensation of the
non-occurrence of the energy release and its effect on a main combustion.
